Control strategies to eliminate the transmission of Chagas disease by insect vectors have significantly decreased the number of reported acute cases in Brazil. However, data regarding the incidence and distribution of acute Chagas disease cases in the State of Pernambuco are unavailable in the literature.
A geographical information system was used to delineate the spatiotemporal distribution profile of the cases from 2002 to 2013 in 185 municipalities of Pernambuco based on the municipality where notification occurred. The results were presented in digital maps generated by the TerraView software (INPE).
A total of 302 cases of acute disease were recorded in 37.8% of the municipalities, for a total of 0.13 cases per 1,000,000 inhabitants per year. Out of the 302 cases, 99.3% were reported between 2002 and 2006. The most affected municipalities were Carnaubeira da Penha, Mirandiba and Terra Nova. The risk maps showed a significant decrease in the number of notifications and a concentration of cases in the Midwest region.
This study highlights a significant decrease in new cases of acute Chagas disease in Pernambuco starting in 2006 when Brazil received an international certification for the interruption of vectorial transmission by Triatoma infestans. However, control strategies should still be encouraged because other triatomine species can also transmit the parasite; moreover, other transmission modes must not be neglected.
通过昆虫媒介消除恰加斯病传播的控制策略已显著降低了巴西报告的急性病例数量。然而，伯南布哥州急性恰加斯病病例的发病率和分布数据在文献中尚无记载。
利用地理信息系统，根据病例通报所在的市，描绘2002年至2013年伯南布哥州185个市病例的时空分布概况。结果以由TerraView软件（巴西国家空间研究所）生成的数字地图呈现。
在37.8%的市共记录到302例急性病例，每年每百万居民中有0.13例。在这302例病例中，99.3%是在2002年至2006年期间报告的。受影响最严重的市是卡瑙贝拉达彭哈、米兰迪巴和特拉诺瓦。风险地图显示通报数量显著下降，且病例集中在中西部地区。
本研究突出表明，自2006年巴西获得因克氏锥蝽媒介传播中断的国际认证以来，伯南布哥州急性恰加斯病新病例显著减少。然而，仍应鼓励采取控制策略，因为其他锥蝽物种也可传播寄生虫；此外，其他传播方式也不可忽视。
